Terminal, base station and communication method

Abstract

A terminal includes: a control unit configured to assume that there are a scheduling cell and a scheduled cell in multi-carrier scheduling by single control information; and a reception unit configured to receive the single control information from the scheduling cell. The reception unit receives a plurality of scheduled cells based on the single control information, and the control unit determines whether or not an unlicensed frequency cell can be configured as the scheduled cell.

1 . A terminal comprising:
 a control unit configured to assume that there are a scheduling cell and a scheduled cell in multi-carrier scheduling by single control information; and   a reception unit configured to receive the single control information from the scheduling cell, wherein   the reception unit receives a plurality of scheduled cells based on the single control information, and   the control unit determines whether or not an unlicensed frequency cell can be configured as the scheduled cell.   
     
     
         2 . The terminal as claimed in  claim 1 , wherein
 the control unit determines that the unlicensed frequency cell cannot be configured as the scheduled cell.   
     
     
         3 . The terminal as claimed in  claim 1 , wherein
 the control unit determines that the unlicensed frequency cell can be configured as the scheduled cell in a case where the unlicensed frequency cell satisfies a specific condition.   
     
     
         4 . The terminal as claimed in  claim 3 , wherein
 the specific condition is a condition that there is a capability of configuring the unlicensed frequency cell as a scheduled cell.   
     
     
         5 . A base station comprising:
 a control unit configured to assume that there are a scheduling cell and a scheduled cell in multi-carrier scheduling by single control information; and   a transmission unit configured to transmit the single control information from the scheduling cell, wherein   the transmission unit transmits a plurality of scheduled cells based on the single control information, and   the control unit determines whether or not an unlicensed frequency cell can be configured as the scheduled cell.   
     
     
         6 . A communication method performed by a terminal, the communication method comprising:
 assuming that there are a scheduling cell and a scheduled cell in multi-carrier scheduling by single control information;   receiving the single control information from the scheduling cell;   receiving a plurality of scheduled cells based on the single control information; and   determining whether or not an unlicensed frequency cell can be configured as the scheduled cell.
